Engine Set Up

[WIL35]

Just a quick question on a 4.2; am I better off with low adaptives (+/-5) and a slightly lumpy idle (@1k rpm, T pots @ 18.3) or a smoother idle, worse adaptives (-20) and uneven T pots? I've now got it with the former setup I just haven't taken it out for a run yet.

Thanks

I'm no expert but I would take it for a run with what you have now. Try to cruise at constant revs to give the ecu time to learn the adaptives, eg hold it at 1500 rpm for a while, then 2000, 2500 etc. and see how it feels. It might idle better after some bedding in
